To all evhom itmc'jconccm ed to be quickly loaded rom a suitablestationary tank containing liquid and thereafter carried to the lace ofthe fire and discharged by a suita le hand pump. To thisend I haveprovided a vessel to contain the liquid, as water or brine, a false headtherefor normally closing the vessel while adapted to be instantlydepressed into it, a )ortable tank normally resting on the false ead andhavin a suitable entrance valve, and a pump an discharge hose carried bythe tank. With such apparatus, in case of fire, it is only necessary toshove down into the vessel the tank until it is filled with liquid andthen carry it to the place of'the fire and operate the pump to dischargethe contents. The invention includes not only this broad idea but alsothe particular features of temporarily holding the false head to thevessel and temporarily securing the tank. to the head and of holding thepump in the tank, all of which will be clear from the descri tionhereinafter given of a preferred embodiment of the invention.

In the drawings, Figure 1 is a perspective view of my fire extinguishingapparatus, the tank being partly broken away to dis close the interior;Fig. 2 is a vertical sec: tion through the upper portion of the vesseland the'lower portion of the tank; Fig. 3 is a horizontal sectionthrough the tank looking downward; Figs. 4 and 5 are details showing theconstruction for temporarily holding the tank to the head, beingfragmentary vertical sections, on the lines 4.4 and 5-5 respectively ofFig. 3; Fi' s. 6 and 7 are side elevations of the clamp or holding thepum in place, being respect-ively a front an rear view with the aparatus as shown in Fig; 1; Fig. 8 is a etail, being a vertical sectionsubstantially on the line 88 of Fig. 7.

As shown in the drawing, 10"repre'sents a barrel which is the vessel forcontaining the stored ext-inguishin liquid, which may be water or brine,or 0t er substance.

11, indicates a false head forthe barrel, the same bein shown as a ieceof sheet metal flanged ownw'ardly at itsl outer edge at 12; This head ishung on the barrel by suitable metal straps 15. Three of these strapsare shown riveted to the head and bent under its flange and thenupwardly,

then outwardl and downwardly to provi e hooks "adapts to extend overftheupper edge of the barrel and thus normally support the head with itsload. The hooks are of comparatively light sheet metal so that anadditional downward pressure on the head may strai to free'the heail thebarrel.

20 indicates a tank which is adapted to receive the extinguishing liquidfrom the barrel, enabling 1t to be conveyed to the place of use. Thistank is preferably in the form of a bucket with a cylindrical wallbottom 21 and a rigid bail 22 at the top which it may be carried. In thebottom of the bucket is a valve 30 controlling an -open-' .ing 24through the bottom and within the bucket and secured by the bail is aThe bucket, with its'pump, normal y stands on the false head 11, asshown in Fi 1.

The bucket is preferably provide on its outer side at the bottom with anoutwardly projecting foot rest 25 on which the operator places his footwhen working the pump. This foot rest is of use also in tempump 40.

ten the hooks sufficiently V enabling it to drop into porarily securingthe bucket to the head 11.

This I accomplish by having an up-turned lip or strap 13 of the falsehead adapted to lie overthe foot rest. Other straps 14 extend oversuitable outward projections on the bucket; Such out-ward projectionsare I shown in Figs. 3, 4 and 5 as made by U- shaped outward bends 26inthe stifi'ening wire 27, which will lie at the base of; the verticalwall where it is curled back to join the bottom 21. The straps 13 and 14normall hold the bucket on the head 21 but enable it I to be easilydetached therefrom.

In caseof fire, a downward ressure by the operator on the bucketstraightens out the hooks 15 so that the head and bucket go down intothe liquid and the bucket becomes filled through-the opening 24. Then,when the bucket is raisedout of the barrel the valve closes andthebucket pulls loose from the head by straightening the retain-' -1ngstraps and, with its contents, may be carried to the place of use. Thisoperation of loading the bucket may be done very quickly. Theop'ei'ator'simply takes hold of the top of the bucket Withhis-hands andpushes it down into the barrel, the. bucket automaticallyfilling. Thefalse head thus becomes submerged in the liquid and when the bucketislifted. out of the barrel the weight of, the water above the projectingportion of thehead insures the straps 13 and 14 bendingto allow thebucket to pull loosefrom the head,

Thevalve which controls the entrance of water into the bucket may bethat shown in' Figs. 1,2 and 3 which is shown, described i at 29, tomake a scatter the valve.

leather 31 rests normally on the highest and claimed in my divisionalapplication No. 708,998, filed July 12, 1912. Such valve consistsof adisk 3O, preferably of metal, having beneath it a pad 31, which ispreferably a disk of leather held in place by an under dislr or washer32 and the central bolt 33., Su-rrounding the opening 24 in the base ofthe bucket ,is'the sleeve 28, which is rolled over outwardly at itsupper end, as shown The point. of the curled-over edge29. Secured to thevalve 30 is a sheetgjmetal strap 35 which bends downwardly and projectsbeneaththecurled edge, 29 to center-the valve,

as well as, to limit its upward movement. Th1s strap 35 1s shown ashaving four arms like a Grreekcross.v At its center this cross,-

is held by thefbolt. 33. At the edges of the 'disk 30 the arms of thecross bend downwardly at right ,angles and then bend in- Wardly beneaththe edge 29. Itis to beenderstood that agreater or less number of armsthan the four shown maybe employed on this strap,.if desired. Notonlydoes this strap maintain the disk in proper position byrallowin it tocasily'move upwardly to limit its li t, but enable.v thedisk to beremoved entirely whenever desired, one or two of the arms bemg simplysprung outwardly at its lower end enough to clear the edge29.

1; The pumpcarried by the bucket and designated 40 in the drawings mayconveniently be lot the differential type shown, wherein there is:avertical barrel terminating at its lower end in the housing 41 carryingasuit able intake check Valve. Operating in-the barrel-is a plungerforming a continuation of i form. The pump is provided with a suitabledischarge tube 47 leading from it at the which: takes onl base of theair chamber'and to this pipe is connected a hose 48' which has a nozzle49.

To hold the pump firmly in the bucket, as wellas'to properly positionthe discharge hose and also to enable the pump to be convenientlyremoved whenever desired I may form thebail 22 in the peculiar mannerand provide it with the clamp, shown particularly in Figs. 6, 7 and 8,and which is shown, described and claimed in my divisional applicationNo. 708,997, filed July12, 1912. 1 will now describe such structure. Atthe base of the air chamber 45, where it joins the pump barrel, is anoutwardly pro'ectin annular shoulder 46. The bail 22 is torme with asubstantially semi-cylindrical portion 50 which is adapted to snuglyembrace Nithin the one side of the pump barrel. semi-cylindrical seatthus provided is a peripheral groove 51 adapted to receive substantiallyhalf of the projecting shoulder 46. On the opposite side of the pumpbarrel 40 is a clamp plate 60 which likewise has a semi-cylindricalbody. At one edge this clamp has an ear 61 which projects between an ear52 of thebail and the main body of the bail53 adjacent to the pointwhere it is secured to the bucket. A pin 55 passing through the ears andinto the portion 53 hinges the clamp to the bail. A suitable thumb-screw58 passes loosely through an opening in an ear 62 on the clamping plateand screws into'a threaded opening 54 in the bail. The bail plate 50 isprovided near its upper edge with a notch 57 in which rests thedischarge tube 47. Accordingly, when the thumb screw '58 is tightened,thepump is clamped in place. It cannot move up or down, due to theprojecting shoulder 46 in the groove 51, nor twist in the bearing, thedischarge tube in the recess 57 preventing any twisting movement.Accordingly, the pump is held in the desired position. By screwing outthe thumb-screw 58, however, the clamp plate may be turned back and thepump, with the hose, entirely removed,

whenever desired.

It ,will be seen from the above description that my fire extinguishingapparatus is sim ple and cheap in construction. It requires no specialcharging and is alwayssubstantially ready. for use. It. is onlynecessary to push the bucket do\vn. into. the barrel,

then carry it to te place of use and operate the pump. In such operationthe operator placeshis foot on the projecting foot rest 25 and raisesand lowers the plunger by means an instantflof time and use. This isaccomplished by simply bending back to the original position 1e straps1.5, 13 and 14 on the head and replacing the head with the stra s 15overhanging the upper edge of the barrel and replacing the bucket on thehead with the straps 13 and 14 overhanging the lateral rejections of thebucket. The free ends the straps 13 and 14 all project in the samedirection-so that, when the bucket is being replaced, the strap 13 willstand in the opening ofthe foot rest 25 with its free end toward thearch of the foot rest and the straps 14 will stand at the rear of theprojections 26 "with their free ends toward them. Accordingly, arearward shove of the bucket in thls position brings all three strapsover the correspond- 15 mg projections of the bucket, holding the bucketin place until next used.

It should be noted that, while I have described the pump and its holdingdevice for the sake of completeness, the present invention isindependent thereof. My self-loading tank may be employed with orwithout the pump, as desired. Also it should be noted that though theadmission valve shown is admirably adapted for this purpose, I am notlimited in the present application to such admission valve. For claimson the specific structure of the admission valve and on the pump holdershown reference should be had to the two divisional applications abovementioned.
